IPC: G11B17/04
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a disk device suited for miniaturization and light weight, and capable of automatically loading/unloading a disk. SOLUTION: A carrying means 300 is provided with a guiding means 200 for supporting a disk 1 movably toward a disk surface, a medium driving means formed so as to have a thin flat plate shape to carry and drive the disk while rocking toward the disk surface, and a synchronous driving means for driving the medium driving means. Since the medium driving medium itself is made thin and needs only to move along the disk surface from a disk feeding position to a position for rotary-driving the disk 1, the necessity of a drawer moving mechanism and an up-and-down moving mechanism is eliminated, and the device is thinned and miniaturized.

IPC: B60H1/00
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To suppress a white fog phenomenon during a cooling operation with ventilation in an inside-outside air dual layer unit type air conditioner for a vehicle. SOLUTION: An inside/outside air introducing mode is selected in a cooling operation mode, an inside-outside air switching door 5 and an inside air open/ close door 6 are controlled so that respective inlets 2, 3, 4 and a communication space 23 are opened. In this way, the inside air and the outside air are mixed together so as to flow into an evaporator 8, so that a temperature difference and a relative humidity difference are reduced after they passes the evaporator 8. Therefore, condensation of water vapor is prevented in the vicinity of a face opening part 12 in which the outside air and the inside air are mixed together again, and a white fog phenomenon can be suppressed.

Abstract: PURPOSE:To use luminous flux efficiently for the formation of interference firnges and to improve detection sensitivity by constituting a diffraction grating so that diffracted light beams of specific degree to be superposed among plural diffracted light beams are almost largest in intensity. CONSTITUTION:Luminous flux emitted by a laser 1 is made incident on a polari zation beam splitter 3 through a collimator lens 2 and split into reflected lumi nous flux and transmitted luminous flux which are almost equal in quantity.

Title: Laminated plate with low radio wave reflection property
Inventor: NAKAJIMA HIROSHI
IPC: B32B7/02
Filed: 1990-02-28
Abstract: PURPOSE:To form a plate-shaped body with low reflectance for a radio wave such as a television broadcasting wave by dividing a diaphragm or a film into pieces each having the specific length on one side. CONSTITUTION:A diaphragm, a film or a plate-shaped body 2 is divided into pieces each having one side of a length equal to or below 0.4 times, preferably 0.3 times the wavelength lambda of a radio wave. When a plane wave is incident on a given scatterer, electrons only vibrate at a given point in tune with the frequency of an incident electromagnetic wave in the scatterer. The position of a portion with a high electron density generated by the vibration of electrons moves and this fact becomes a factor for reflecting the electromagnetic wave. A region wherein electrons can freely move is made smaller by reducing the ratio L/lambda by dividing the plate-shaped body 2 and, as a result, the reflecting quantity per unit area decreases. Thus, the reflectance for electromagnetic wave by a laminated plate is reduced and radio wave interference can be reduced as little as possible.

Abstract: PURPOSE:To make it possible to detect the fundamental period of an AC signal in a wide frequency range, by inputting the AC signal to one of a level comparator and by sample-holding positive and negative crest values obtained by phase inversion of the AC signal and inputting them to the other of the level comparator. CONSTITUTION:AC signal Vin 1 is connected to one input terminal of level comparator CMPA4. Meanwhile, signal Vin 1 is inverted by phase inverter INV1, and output signal 2 is input to SH circuit S1 which is constituted by buffers A1 and A2, attenuator A3, switch SW1, and sample hold SH capacitor C1. Output signal 3 of circuit S1 is input as reference voltage Vref to the input end of CMPA4. Output signal 4 of CMPA4 is connected to trigger pulse former T1, and trigger pulse 5 is generated each time signal 4 is inverted, thereby controlling switch SW1. Since the reference voltage value is set to a negative DC voltage value and a positive DC voltage value in section t1 for a positive input signal and section t2 for a negative input signal respectively, the output of CMPA4 is not inverted unless the output of CMPA4 exceeds the reference voltage in the next opposite phase when the level of CMPA4 is inverted, so that malfunctions can be prevented.
